RTS 23: Instrument Reference Data

MiFID II introduces a requirement for trading venues to provide instrument
reference data to their National Competent Authority (NCA), which for Cboe
is the FCA. This data will then be sent to ESMA to publish. The reference
data provided by Cboe will cover relevant characteristics of those
tradeable instruments that are admitted to trading on Cboe and will be sent
for each segment MIC operated by Cboe.

Cboe currently provides symbol reference files for customer use.
Cboe will continue to do so, without adding the additional data
elements required in the regulator submission to this file. Cboe
will also provide machine-readable reference data files as part of
meeting our Best Execution
obligations.
